MELBOURNE, Dec. 1 -- Origin Energy Ltd., Sydney, has confirmed an extension to the Trefoil gas discovery in the Bass basin permit T/18P off northern Tasmania with success at Trefoil-2 appraisal.

The company says several gas-bearing sands were intersected within the Eastern View Coal Measures and these will be analyzed more fully over the next few weeks using cores, wireline logs, reservoir pressure readings, and well samples.

The well has confirmed the continuity of the reservoir sands between the Trefoil-1 discovery and the Trefoil-2 well. The size of the resource will be determined when all the new data has been evaluated.

The Kan Tan IV semisubmersible rig is now moving to drill the Rockhopper-1 wildcat about 12 km to the north.

Both Trefoil and Rockhopper are close to the company’s producing Yolla gas-condensate field.

Origin is operator with 39%. AWE Ltd., Sydney, has 47.5% and Innamincka Petroleum Ltd., Brisbane, has 5%.
